There's an issue with this release regarding the pistols, seems something went wrong during the export, as none of the child objects/meshes are in the fbx Can still export it from the blend ofc, but I'm mostly just letting you know!
Hi! One user had reported this issue a few hours ago. I'm on vacation now, but I'll try to get access to a computer, install everything and fix them. This should be fixed within 24 hours. I'm sorry for the inconvenience it brought upon you :(
I was able to get access to a laptop, but it was too low-end to run Blender and the Blender would crash every time I open it, so I wasn't able to fix the issue today. I'm hoping to have better luck with a different computer tomorrow
